BOTTLE-FILLING MACHINE.

Specification of Letters Patent.

Application led April 19, 1915. Serial No. 22,318.

To all whom it may concern Be it known that I, CHARLES A. YOUNG- MAN, acitizen of the United States, and a resident of Louisville, in thecounty of J efferson and State of Kentucky, have invented cert-ain newand useful Improvements in Bottle-Filling Machines, of which thefollowing is a specification.

My invention relates to the bottling of liquids, and one of the mainobjects thereof is to provide a machine for such purpose which willcontrol the quantity of liquid admit-ted to each bottle or otherreceptacle.

A' further object is to provide means whereby this result will beaccomplished-by gravity of the liquid to be bottled; and other objectsare to provide such machines which are simple in construction, positivein operation, composed of but few parts not likely to get out of orderto require repair,l Vand comparatively inexpensive.

My invention is fully described 1n the following specification, of whichthe accompanying drawings form a part, in which the separate parts aredesignated by the same reference characters in each of the views, and inwhich Figure 1 is a front elevation of a machine constructed inaccordance with my invention; Fig. 2 is a partial plan view thereof, ona reduced scale; Fig. 3 is a fragmentary view of the rear thereof; Fig.4 kis an end elevation thereof; Fig.- 5 is an enlarged, longitudinal,vertical, central, section through one of two cylinders which I employ,and its connected bottle f lling nipples and valves; Fig. 6 is a sectiontaken on'the line 6 6 of Fig. 5;' Fig. 7 is a section taken 'on the line7 7 of Fig. 5; and Fig. 8 is a detached, perspective, view of one valve.

In the drawings forming a part of this application I have shown oneformof embodiment of my invention, comprising a frame orv support 9havingtwo cylinders 10 and l1 mounted thereon andin' the same axialplanes, each of vsaid cylinders having a piston 12 slidabletherein,nonly one of which is shown, and which pistons are connected bymeans-of a common piston rod 13 slidablein suitable stuiiing-boxes 14.Each of said piston cylinders has two valve casings at the lower sidethereof, 15 and 16 for the cylinder 10 and 17 and 18 for the cylinder11, corresponding valves 15a, 16a, 17a, 18a, and nipples 15b, 16", 17h,18", being contained in the respective casings, and-each of said casingsis in communication with a liquid feed pipe 19 from an elevatedreservoir 20 bymeans of branching tubes 15C, 16C, 17C, and 18", wherebythe supply of liquid-is constant to each casing. Y

Longitudinally adjustable in tubes 21 secured to the cylinder 10, Fig.2, is a yokeshaped frame 22 adapted to be locked in deslred relationshipwith saidvcylinder by means of set-screws 23,l the cylinder l1 beinglikewise provided with similar tubes 24, yoke-'shaped frame 25, andset-screws 26, and the cross-heads of said frames 22 and25 are in thedirect line of lthe corresponding ends vof the piston rod 13 and serveto limit the movement vof the same in either direction,

the' reservoir 20, a toggle-leverarrangement 29 being provided`thereunder for moving both ends of said platform simultaneouslyupwardly or downwardly, a handle 30 being 'provided onv one ofthe leversfor such platformmovement, and I also provide a ratchet 31 whereby" theplatform 27'1nay `be adjustably held at any desired heightq 'In view 'ofthe fact that all of the valve casings and contained valves are exactlyalike, a description of those `on'the cylinder 10 will suflice;'eachcasing is provided with two distinct ports 32 and 33 communicating thevalve bore 3aA with a passage 35 for the casing 15 and 36 for the casing16 in the wall of the cylinder 10 and which passages communicate withcorresponding ends of said cylinder, one oneach side of the piston 12.'y n Each of the valves is provided with a passage 37 adapted tolcommunicate the port 32 Vwith-the corresponding branch tube 15 or 16e,-whereby the liquid from the reservoir will flow into the cylinder 10,but one of said valves is turned to closethis communication while theyother is open thereto, for a reason to be explained; each of saidvalves has, also, a port 38 adapted to be placed in communication withthe respective port 33 in one position and being in constantcommunication with the corresponding nipple 15c or 16C through a bore10, and it will thus be seen that each nipple may be placedin'communication with the Patented Jan. 2, 1917.

respective cylinder passages, and, when said" branchtubes are open tosaid cylinder passages, said nipples are out of communication with saidcylinder passages; in the arrangement illustrated, the nipples are incommunication with the cylinder passages when vertically arranged,whereas they are out of such communication when inclined, as in Fig. 7and the branch tubes vare then in communication with the correspondingcylinder passages.

Assuming the parts to bein the positions shown in Fig. 5 with theexception of the piston which is assumed to be in the position indicatedby dotted lines; if, now, the liquid from the reservoir be allowed topass therefrom, a suitable cock being provided thereior although notshown, said liquid passes to the vbranch tubes, through the passage Bofthe valve 15a, port 32, and cylinder passage 35,. to the cylinder 10, onthe left of the piston, but no liquid passes through the valve 16a forthe reason that the passage 37 thereof is turnedv to close offcommunication between the corresponding branch pipe and the cylinderpassage 36; the latter passage, however, is in `communication with thenipple 16h, and the liquid in the cylinder, if

any, tothe right of the piston is free to escape from thev cylinder.This, however, creates a partial vacuum in this portion of the cylinderwhich tends to prevent such liquid escape until the liquid entering thecylinder onY the other side oi' the piston moves said piston into theposition Vshown `in full lines,lthus forcing the liquid through thenipple 1Gb, and into the bottle thereunder, this movement of the pistonbeing limited bythe set positions of the yokes 22 and 25, and the amountof liquid so forc'edrout of the cylinder being thus gaged. When thisquantity of liquid has been forced into the bottle, said bottle isremoved, such removal tending to throw the nipple 16b from vertical toinclined position, thus reversing the valve 16:l and closing nipplecommunication but opening the branch tube communication; an empty bottleis then placed Ybeneath the valve casing 15 with the nipple therein,this moving said nipple from inclined to vertical position, and openingnipple communication with the cylinder and closing reservoircommunication, and the liquid being admitted to the cylinder on the'right of thepiston moves said piston'rback to the position indicated bydotted lines in Fig. 5, thereby forcing the liquid from the cylinder attheleft of the piston into the new bottle, and this substitution ofbottles beneath the valve casings 15 and 16 alternately continues.

Inasinuch as one cylinder and connections would only occupy onejhan'd ofthe operator, I provide two such cylinders and connections, and,toinsure complemental piston op- -eration in the two cylinders, and thussimultaneous bottle removal and substitution for both cylinders, Ianchor the two pistons upon the same piston rod.

In View of the retarding eiiect of the partial vacuum createdlalternately upon each side of the respective cylinderV pistons, it willbe obviousv that therel must 4be piston movement', and, if I providemeans for limiting the piston movement, it will be apparent that I alsocontrol the quantity' of liquid forced out of each cylinder into the'corresponding bottles; this 'piston movement, as has been described,4is' due to the flow of liqiiid into the cylinders, Yupon opposite sides,of the pistons alternately, and I therefore have my liquid reservoir ata considerable height above the bottle lling machine, the higher thebetter to correspondingly lincrease the head Vof the liquid; Y

In' order to prevent the operator from moving the nipple too 'far ineach operation,

I provide a stop 41 for' each of the valves',

but this is of old and well l'niownV construction and any suitable' formthereof maybe employed. Two bottles are thus being filled at one time,two bottles-are removed at onetime, and twov bottles are substitutedvatone time, this substitution being with the A valves of each cylinderalternately, v the re'- i'noval of bottles closing 0E Vthe `flow kofliquid from the cylinders, but opening the flow' of liquid thereto',wl'iereas"theA substitution of bottles opens the valvesto permit liquidto flow thereto, `and closes oflfthe liquid supply to said cylindersthrough the 105 Vvalves actuated'. A

It will be seen thatjmy invention includes the "creation of partialvacuums, and also ini. volves the law of gravitation, and I reserve theright to' any mechanismwhatever which 11() produces the desired resultsby the inclusion of these t'wofeatures.

Having fully described myH invention, M what I claimas new, and desireto secureby Letters Patent, is 115 1. A bottle' filling machine,comprising 'a pair of cylinders, a piston in each cylinder, a rodconnecting said pistons and having,L ends projecting outwardly of saidcylinders, i
